... As of October 1, 2009, the global rate for the STIS NUV-MAMA dark current has still been occasionally reaching values as high as 13500 counts/s. This high dark current will force use of a signficantly smaller buffer time than would be otherwise needed, and in many cases may push the count rate high enough to make time-tag observations impractical. ... However, we instead found for the NUV MAMA detector an initial global dark rate of between 9000 and 18000 counts/s (a mean of 0.013 counts/s/pixel). ...

CFITSIO Interface Library CFITSIO is a library of ANSI C routines for reading and writing FITS format data files. ... The CFITSIO library is built on Unix systems by typing: > ./configure [--prefix=/target/installation/path] > make (or 'make shared') > make install (this step is optional) at the operating system prompt. The configure command customizes the Makefile for the particular system, then the `make' command compiles the source files and builds the library. ...

... NOW HERE'S THE BEEF: The VSWR tolerance of a transmitter like ours depends on a number of potential problem areas, such as plate voltage swing, voltages and currents in the elements of the matching network and filter, voltage and current tolerance at nodes in the Heliax line, etc. ... The screen grid has a finite power dissipation limit (before it starts melting!), and this limit is given on the tube datasheet. Transmitter metering should show both screen voltage and screen current. ...

... This limited extent suggests that the currents which disturb the field flow somewhere nearby, probably near the auroral arcs. ... Any electric current, however, must flow in a closed circuit, and since it seemed to be caused (like that of the aurora) by processes taking place in distant space, Birkeland proposed that it came down from space at one end of the arc and returned to space at the other end. ... The electric energy needed to drive the current is taken from the motion, which is slowed down....
